An apparatus for pivotally supporting a transducer or other device to a boat transom including a mounting bracket having a base portion for attachment to the boat transom, the mounting bracket having integral parallel left and right wing portions extending from opposite ends thereof each having an aligned opening therein and including an integral tubular collar around each opening, a pivot bracket including a base portion to which a transducer or the like may be attached, the base portion having integral left or right wing parallel portions extending from opposite ends thereof, and each having an aligned opening therein and including an integral tubular collar around each opening, the pivot bracket being positioned within the mounting bracket with the tubular collars in alignment, and a pair of coil springs, one positioned within the left tubular collar of the pivot and mounting bracket and the other positioned in the right tubular collars of the pivoting and mounting brackets, the external diameter of the coil springs being slightly less than the internal diameter of the collars so that the springs serve as an axial for the rotation of the pivot bracket relative to the mounting bracket, one end of each of the springs being affixed to the mounting bracket and the other end being affixed to the pivot bracket, the springs providing resilient biasing force rotating the pivot bracket relative to the mounting bracket towards the rest position.
